DOUBLE-SHOVEL PLOW.

SPECIFICATION forming part of Letters Patent No. 782,395, dated February14, 1905.

Application filed September 23, 1904. Serial No. 225,664.

T0 at whom it may concern.-

Be it known that I, ALFRED F. HEROD, a citizen of the United States,residing at North Springs, in the county of Jackson and State ofTennessee, have invented certain new and useful Improvements inDouble-Shovel Plows, of which the following is a specification.

This invention appertains to agricultural implements of the typedesigned chiefly for cultivating and tilling the soil,and aims toprovide a device for the purpose aforesaid which will operate equallywell in rich or poor soil, and particularly inland abounding in gravel.The invention aims to devise an implement of simple construction andcapable of adjustment to admit of changing the pitch of the teeth orshovel-blades according to the nature of the soil and the character ofthe work, whereby the cultivation may be deep or shallow, as desired. i

For a full description of the in vention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which- I pFigure 1 is a perspective View of adoubleshovel plow constructed inaccordance with and embodying the essential features of the invention.Fig. 2 is a side view thereof. Fig.3 is a detail perspective view of therear portion of a beam, a standard, a handle-bar, brace, and

the means adj ustably connecting the standard with the beam, the partsbeing separated and arranged in a group. Fig. 4 is a top plan view ofthe proximal ends of the stock and beams, showing the intermediatespacing devices and the connecting means. Figs. 5, 6, and 7 are in allthe views of the drawings by the same reference character.

The implement in its general structure comprises'a stock 1, companionbeams 2 and 3, standards 4, handle-bars 5, braces 6, and adjustableconnections between the standards and beams, the same consisting ofthreaded rods 7 and pairs of set-nuts 8 and 9, the latter embracingopposite sides of the standard and :sembled. The clevis 10 has itsforward portion provided with a vertical series of openings to enableapplication of the draft at any required point. The beams 2 and 3 aretransversely spaced and their foward ends are ar ranged upon oppositesides of the rear part of the stock 1 and are bolted or otherwisesecured thereto. The handle-bars 5 are pivotally connected at theirlower ends to the front portion of the beams and are stayed by means ofthe braces 6, which are pivotally connected at their lower ends to saidbeams and have adjustable connection at their upper ends with thehandle-bars. 'As shown, thebraces 6 are provided with a series ofopenings 12, through any one of which bolts or like connections 13 areadapted to be passed for securing the braces to the handle-bars in therequired adjusted I position.

The standards 1 are similarly constructed and are provided attheir lowerends with shovel-blades 1 1 of any desired pattern or make, according tothe nature of the soil or particular work. The standards are pivotallyconnected at their upper ends to the rear eX- tremities of therespective beams to admit of the pitch or inclination of the shovels 1 1being regulated to meet special requirements. As shown, the rear end ofeach beam is cut away at 15 to receive the upper ends of the standard,which is pivotally connected thereto in any substantial manner; Abrace-rod 7 connects each standard with its respective bring the gripsat their required height, after which the braces 6 are connected to thehandlebars by the bolts or fastenings 13. One of the bolts, as 13, isshorter than the other, thereby throwing the standards and plow-pointsof the shovels in advance of each other, which is of advantage in themanner well understood in the art. 1

To admit of lateral adjustment of the beams 2, so as to space theshovels apart a greater or less distance, spacing devices are interposedbetween the stock 1 and the forward ends of the beams 2. These spacingdevices consist of wedges 16 and blocks 17. The wedges 16 are flanged attheir upper edges, as shown at 18, to overlap the stock 1 to assist inmaintaining them in proper position and to give proper direction intheir longitudinal adjustment. Each wedge is'formed with a longitudinalslot 19, through which the bolts or fastenings 20 pass. The spacers 17are located in the rear of the spacers 16 and may constitute fulcra forthe beams 2 when using the wedges 16 for adjusting the front ends of thebeams. The spacers 17 are adjustable, so as to be lengthened orshortened to vary the distance between the stock 1 and the beams 2. Eachspacer 17 is composed of blocks 21 and 22. One of the blocks, as 22, hasa tongue 23 at its inner end,

and the other block is formed in its end with intersecting grooves 24and 25 of different depths for reception of the tongue 23. The blocks 21and 22 are centrally bored to receive a bolt or fastening 26, by meansof which the beams 2 and stock 1, as well as the handle-bars 5, areconnected. When it is required to vary the distance between the shovelsor to adapt the implement for shovels of different widths, the beams 2may be spread more or less at their rear ends, either by longitudinaladjustment of the spacers 16 or by lengthening or shortening the spacers17 or by a combined adjustment of both sets of spacers. When the bolt orfastening 26 is loosened to admit of separating the blocks 21 and 22 topermit the tongue 23 to clear the grooves of the block 21, one or theother of said blocks may be turned to admit the tongue 23 entering thegroove of proper depth, so as to secure the proper lengthening of thespacers and lateral adjustment of the beam. After the adjustment hasbeen effected the fastenings 26 and 20 are retightened.

Having thus described the invention, what
